Answer

Patients with MSA have a poor prognosis. The disease progresses rapidly. Median survivals of 6.2-9.5 years from the onset of first symptoms have been reported since the late 20th century. No current therapeutic modality reverses or halts the progress of this disease. MSA-P and MSA-C have the same survival times, but MSA-P shows more rapid dysfunctional progression.

An older age at onset has been associated with shorter duration of survival in MSA. The overall striatonigral cell loss is correlated with the severity of disease at the time of death.

Bronchopneumonia (48%) and sudden death (21%) are common terminal conditions in MSA. Urinary dysfunction in MSA often leads to lower urinary tract infections (UTIs); more than 50% of patients with MSA suffer from recurrent lower UTIs and a significant number die of related complications. [20]
